Anyone got a view on these high yielders?

All, was chatting with a friend yesterday, and shes holding these income stocks.

DPST => Direxion Daily Regional Banks Bull 3X Shares, trading at less than book, 4.5% dividend.

EFC => Ellington Financial Inc., 14.5% dividend

ORC => Orchid Island Capital, Inc. 18.7% dividend

QYLD => Global X NASDAQ 100 Covered Call ETF, 11.7% yield

Its not clear if these companies can sustain their dividends. They might, maybe/maybe not.

Anyone got a view on any of these?
